This is an early preview of me and a co-developer, Jian Rong on the route of Pasir Ris - Bedok route (Part 1, due to 10 minutes limit imposed by Youtube, I have to shorten the video til Tanah Merah. I will be uploading the part 2 soon).
I would appericiate for your kind understanding in errors may not be resolved yet, since this is an early preview.
PS: New version is available soon!
